Etymology: "Pathophysiological" is a modern compound, built from "patho-" plus "physiological." The first half comes from Ancient Greek "pathos," meaning suffering, feeling or experience, related to the verb "paskhō," to suffer. The second half traces back to "physis," nature or growth, combined with "-logia," the study of something, which gave English "physiology" as the study of how living bodies function. "Physiological" adds the adjectival suffix "-al" to that Greek-derived stem, through Latin "physiologicus." The prefix "patho-" entered English as a combining form in medical vocabulary, used to build terms about disease. Attaching it to "physiological" yields a word meaning the functional processes of the body as they are disturbed by illness. The compound is a deliberate technical coinage from classical roots, not a term that ancient Greek or Roman physicians ever used.
